There are four agents of erosion:
The four agents may be aided by gravity, which is the force involved, but a piece of paper sitting on a desk is not eroded by gravity acting upon it, is it? I'm not entirely sure what the other force you speak of could be, but be sure that the above four are the cause of all erosion.
Rainfall, Water, Wind, Ice, and Gravity
Erosion
Wind, water, and ice are common forces that cause erosion and transport sediment from one place to another. These forces can wear away rock and soil through processes like abrasion, and can carry the sediment in the form of sediment loads or suspended particles to new locations.
Three forces that cause erosion are wind, water, and ice. Wind erosion occurs when wind carries sediment and wears away rocks. Water erosion happens through the force of flowing water which can transport sediment and carve out channels. Ice erosion, known as glacial erosion, occurs when glaciers move and scrape against the Earth's surface, picking up and carrying sediment.
Two forces through which ocean waves cause erosion are hydraulic action, where the force of the water breaks rock particles away from the coastline, and abrasion, where these particles are then carried and used to wear away the coast.
Water and wind are two forces that cause erosion. Water can wear away rocks and soil through processes like rivers and waves, while wind can transport and deposit sediments through processes like abrasion and suspension.
Two forces through which ocean waves cause erosion are hydraulic action, where the force of the waves hitting the shore dislodges and removes rock particles, and abrasion, where particles carried by the waves wear away the coastline by scraping and scouring the rocks.
Two forces that cause erosion are water (such as rivers, waves, and rain) and wind. Water can wear away rocks and soil through its force, while wind can carry particles and abrade surfaces over time.
Two forces that cause landforms are erosion, which is the wearing away of rock and soil by natural processes like wind and water, and tectonic forces, which involve the movement of the Earth's plates resulting in the formation of mountains, valleys, and other landforms.
The two ways in which waves cause erosion are deflation and abrasion.
Wind,Water,Ice and (uncommon) Gravity.
The two primary forces that cause erosion through ocean waves are wave action and currents. Wave action, generated by wind, impacts the shoreline, breaking down rocks and sediments through constant battering. Additionally, ocean currents can transport these eroded materials away from the shore, reshaping coastal landscapes over time. Together, these forces contribute significantly to coastal erosion.

The two types are erosion
By erosion. Heat, wind, water are some possible natural forces which cause erosion.
The two spheres that are responsible for erosion are the hydrosphere and the atmosphere. These spheres interact all of the time.
